Measurement of $\hat{I}{ž}_c^{+}$ production in $p$Pb collisions at $\sqrt{s_{NN}}=8.16$ TeV at LHCb

Abstract

A study of prompt $\hat{I}{ž}_c^{+}$ production in proton-lead collisions is performed with the LHCb experiment at a centre-of-mass energy per nucleon pair of 8.16 TeV in 2016 in $p$Pb and Pb$p$ collisions with an estimated integrated luminosity of approximately 12.5 and 17.4 nb${}^{-1}$, respectively. The $\hat{I}{ž}_c^{+}$ production cross-section, as well as the $\hat{I}{ž}_c^{+}$ to $\hat{I}{›}_c^{+}$ production cross-section ratio, are measured as a function of the transverse momentum and rapidity and compared to latest theory predictions. The forward-backward asymmetry is also measured as a function of the $\hat{I}{ž}_c^{+}$ transverse momentum.
